LYOURGUS BUBNHAM, F W'OBUBN, ASSIGNOR OF ONE-HALF TO WALTER L. FRENCH, OF BROOKTON, MASSACHUSETTS.

COMBINED CANE AND CAMP-STOOL.

SPECIFICATION forming part of Letters Patent No. 236,670, dated January 18, 1881.

Application filed July 2, 1880.

To all whom it may concern Be it known that I, LYCURGUS BURNHAM, of Woburn, Massachusetts, have invented a new and useful Improvement in a Combined (Jane and Camp-Stool; and I hereby declare that the following specification and the accompanying drawing give a correct description of the same.

My improvement is supplementary to the invention of D. B. Reynolds, patented August 14,1877. The combined cane and camp-stool described in said patent consists of a knob or ball, which is the head of the cane, and three detachable lengths of wood or other suitable material, which are fastened together end to end and to the knob to form the cane.

To form the camp-stool, the three lengths of the cane are first detached from each other and then screwed or otherwise inserted into suitable holes in the knob, so as to form a tripod. Then into three or more other holes properly located in the knob are inserted standards, which serve to support a flexible seat.

My invention relates entirely to the knob or head of the cane above mentioned, and my object is to construct the same so as to combine the three requisites of strength, lightness, and convenient size. The knob has heretofore been made of wood, which material is suitable as to lightness, but has been found not sufliciently strong. It was considered impracticable to make it of metal, because a solid metallic ball, if large enough for a handle, would (ModeL) be too heavy, and it made hollow the shell would necessarily be too thin to give sufficient 5 support to the legs and standards before mentioned.

The nature of my invention consists in making a hollow metallic knob of the proper size and weight, and furnishing the same with cer- .0 tain internal projections or bosses to be described.

The figure represents the knob and part of the shaft of the cane, and also a partial vertical section of the knob, showing one of the 5 internal bosses.

The bosses B are cast in one piece with the shell A, and are so located that the holes 0, made in the knob to receive the legs and standards, extend into the said bosses. Thus the holes may be of sufficient depth to give adequate support to the legs and standards, and still the shell may be thin enough to give the required lightness.

NVhat I claim is In a combined cane and camp-stool, composed essentially of a spherical head and a canebody, formed in three sections, adapted to be coupled to the head. to form a tripod, the hollow metallic ball A, havinginternal bosses, B, arranged substantially as described, and for the purpose set forth.

LYGURGUS BURNHAM.
